no 3 numbers add to equal 10 and multiply to equal 40.

Multiply the numbers at the top of the fractions. Multiply the numbers at the bottom of the fractions. Write these new numbers as a fraction. So, for example, 1/2 * 2/3 = (1 * 2) / (2 * 3) = 2/6 Now it may be possible to simplify the new fraction. Here 2/6 simplifies to 1/3 (both numbers are evenly divisible by 2). Another example: 2/5 * 3/4 * 7/8 = (2 * 3 * 7) / (5 * 4 * 8) = 42/160 = 21/80

Two numbers you could multiply to get 213 are 71 and 3.
The answer is 105 because 3,5, and 7 are all prime factors and when you multiply the numbers together it comes out to be 105 witch is lower than 160 and is an odd number.
